    Notes: Abstract Chromosome counts and detailed karyotype analyses are presented forI. attica (2n = 16), andI. mellita andI. reichenbachii (both 2n = 24). Karyotypes differ in symmetry, number of telocentrics, occurrence of heteromorphic chromosome pairs, etc. For Western Anatolia first unequivocal records ofI. attica and local differentiation ofI. mellita are demonstrated. The Balkan and West-UkrainianI. reichenbachii appears not to be indigenous to Anatolia.

    Notes: Abstract Information and illustrations on somatic chromosomes, structure of interphase nuclei and hair development are presented for 9 genera and 14 species ofAnnonaceae. A few suggestions tend to improve the unsatisfactory current classification. The spectrum of polyploids found in the family ranges from neo- to meso- and paleopolyploids.

    Notes: Abstract Comparative morphological, karyological and chorological studies prove the distinctness of the SE European and Asiatic populations ofPulmonaria mollis s.l., to be treated asP. dacica (Figs. 4, 5).P. mollis s.str. is interpreted as a relatively young taxon, which probably has evolved from an older stock ofP. dacica ancestors during the Pleistocene (Figs. 6, 8) and might have migrated, perhaps with oak woodland communities, from SE to C. Europe. A similar evolution can be postulated for S—SE European dysploidP. rubra-carnica-stiriaca-vallarsae group; this may have involved still unknown tetraploids (P. carnica?, Fig. 7). This group is linked via the hypertriploid speciesP. vallarsae with theP. saccharata group and at least the eastern species of theP. australis group. The monotypic genusParaskevia apparently marks the earliest divergence from the common Tertiary ancestral stock (Fig. 8). It exhibits a tetraploid chromosome number (2n = 28) but has preserved the most primitive characters. — Some comments on the systematics and nomenclature ofP. australis andParaskevia are added.

    Description / Table of Contents: Summary Chromosomes, relationships, and evolution of tropical woody plants, II.Himantandraceae. 1. Galbulimima, the only genus ofHimantandraceae has 2n=24 in NE-Australia as well as in New Guinea. The karyogram (fig. 1d) is primitive and possibly indicates ancient tetraploidy (paleopolyploidy).Degeneriaceae also have 2n=24. 2. The development of the characteristic multicellular peltate scales ofGalbulimima is demonstrated (fig. 2). Similar scales are found i. a. inAnnonaceae. 3. The distribution ofGalbulimima is centered on New Guinea and extends to the Moluccas Islands and northeastern Queensland (fig. 3), areas particularly rich in ancient relic types. 4. On the basis of broad comparisons of morphological, palynological, anatomical, phytochemical, and cytological characters and their probable phylogenetic progressions (p. 49) the position ofHimantandraceae as a depauperate relic group withinMagnoliales s. str. is considered. We propose the following „natural“ grouping: 1)Winteraceae; 2)Degeneriaceae, Himantandraceae; 3)Magnoliaceae; 4)Annonaceae, Canellaceae, Myristicaceae; 5)Eupomatiaceae.
    Notes: Zusammenfassung 1. Galbulimima, die einzige Gattung derHimantandraceae hat sowohl in NO-Australien als auch in Neuguinea 2n=24. Das Karyogramm (Abb. 1d) ist primitiv und deutet möglicherweise auf weit zurückliegende Tetraploidie (Paläopolyploidie). Auch dieDegeneriaceae haben 2n=24. 2. Die Entwicklung der charakteristischen vielzelligen Schildhaare vonGalbulimima wird dargestellt (Abb. 2). Ähnliche Schildhaare treten u. a. bei denAnnonaceae auf. 3. Die Verbreitung vonGalbulimima ist auf Neuguinea zentriert und reicht bis zu den Molukken und ins nördliche Queensland (Abb. 3); diese Räume sind besonders reich an altertümlichen Relikten. 4. Aufgrund eines breiten Vergleiches morphologischer, palynologischer, anatomischer, phytochemischer und cytologischer Merkmale und ihrer vermutlichen phylogenetischen Progressionen (S. 49) wird die Stellung derHimantandraceae als einer verarmten Reliktgruppe innerhalb derMagnoliales s. str. überprüft. Wir schlagen die folgende „natürliche“ Anordnung vor: 1)Winteraceae; 2)Degeneriaceae, Himantandraceae; 3)Magnoliaceae; 4)Annonaceae, Canellaceae, Myristicaceae; 5)Eupomatiaceae.

    Notes: Zusammenfassung In der vorliegenden Studie sind die Ergebnisse, welche aus der Durchsicht oberösterreichischer Herbarien gewonnen wurden, zusammengestellt. Demnach können für dieses Bundesland fünfPulmonaria-Arten als belegt gelten:P. angustifolia, P. kerneri, P. mollis-Gruppe,P. obscura undP. officinalis, sowie ein Bastard:P. angustifolia×P. officinalis. Allerdings fehlen fürP. angustifolia schon seit längerer Zeit Meldungen über Wiederfunde. Weiters war es möglich,P. kerneri für Oberösterreich festzustellen, welche Art hier früher stets mitP. angustifolia bzw.P. mollis-Gruppe verwechselt wurde. Konnten für die behandelten Taxa, welche auch kurz beschrieben wurden, meist nur Hinweise auf ihre Verbreitung gemacht werden, so war es im Falle vonP. kerneri möglich, neue Fundortsangaben zu ermitteln und eine Punktkarte zu zeichnen (s. Abb.). Schließlich wurde unter Berücksichtigung der gewonnenen Erkenntnisse für die oberösterreichischen Sippen ein Bestimmungsschlüssel erstellt.
